There just is not enough detail to say why it's happening. Even seeing
the output of the banner on the console menu would be more than we're
seeing here. Going on pure speculation only gets us so far.
As below. Connecting a PC to sis0 (through a switch) will get an IP
(10.0.0.100) however and through the web page I can ping external address's
yet I cannot complete a connection to any external website. I will do a
reset to factory defaults, get a laptop connected to the LAN and do some
more testing.
After the #4 reset what do you suggest as my next 3-5 steps?
